Does it need time to cool down. That would indicate hardware issue. What computer/wifi card it has.

There is no wifi card . Direct connection Only.
I have replace wires,modem,router and still is not working well.

More info may help getting added responses....

What changed - it was working fine .. then ...
Updates? Installed new App/Hardware - Kernel etc.. ? ??

The last time it worked - do you have a backup (Systemback in LL3.x)  reverting back may help alleviate..

Any config changes to the router? Specific changes to the network card - i.e. static or dns entries....

What type of card / driver  - could start with the output of

Code:

inxi -n

What Kernel version

Code:

uname -r

Something else to try - if all else...
It being a desktop - could also try a pci NIC card to rule out hardware - perhaps the onboard is going bad???
